Power Management


The number of powered control modules, sensors, actuators, and motors distributed throughout today’s automobiles has increased markedly within the last decade. This has increased the need for more diverse power management and voltage regulation circuits We offer many types of PMIC, DC-DC converter, and voltage regulator devices for automotive power management applications.



Applications


ECU Power Management and Voltage Regulation

As increasing numbers of control modules, sensors, and actuators are distributed throughout the vehicle, voltage regulators and DC-DC converters are needed to manage the power at the point of load in each device.

Automotive PMICs
High Voltage (Direct Battery Connect) Step-Down Switching Regulators
Low Voltage Step-Down Switching Regulators
Step-Up Switching Regulators for Automotive
Linear Voltage Regulators for Automotive

Power Management for ADAS

Our automotive-qualified voltage regulators, power management ICs (PMICs) and power protectors address ADAS power requirements and comply with the CISPR 25 Class 5 EMI standard while meeting the needs for high efficiency and small footprint.
